RING-SPINNING FRAME.

SPECIFICATION forming* part Of Letters :Patent N0. 240,731, dated .April 26, 1881.

Application ined caoba-28,1880. (No model.)

To all whom it may concern:

Beit known that I, OHARLEs C. KENT, of

Laurel, PrinceGeorge county, State of Maryland, have invented certain new and useful Improvements in Ring-Spinning Frames, of

which the following is a specification.

In ring spinning frames, as usually constructed, the twist putinto the yarn is confined, for the most part, to that portion of the yarn between the traveler and the guide-wire. Whatever amount of twist passes back to the yarn between the guide-wire and the rolls is materially lessened; consequentlythe yarn between the rolls and the guide-wire is weaker than it is between the guide-wire and the traveler, and is less able to withstand the draft and inequalities of tension. As a matter of fact the breakage of .the yarn usually occurs between the guide-wire and the rolls, and is due, mainly, to the cause above mentioned. It has been essayed heretofore to carry the twist back beyond the guide-wire. In most instances of which I have `knowledge the device for this purpose, whether attached to the spindle or bobbin or otherwise arranged, has received a positive movementof rotation not derived from the yarn. In one or two instances it has been proposed to employ an auxiliary ring and traveler between the main traveler and ring and the guide-wire; but the auxiliary ringhas been of the same diameter as the main ring, and has been placed around the spindle at a point just above the upper limit of movement of the main ring. This arrangement is inconvenient for several reasons, mainly because the auxiliary ring is very much in the way. The auxiliary device, moreover, is not effective to the desired degree, inasmuch as it is placed at a considerable distancefrom the guide-wire,and this distance, owing to the size of the ring, is necessary, inasmuch as a ring and traveler of that size, if placed close below the guide-wire, would be virtually inoperative.

It is my object to combine with the main traveler, the guide-wire, and the rolls, an auxiliary traveler which shall be situated atapoint above the spindle or bobbin, inclose proximity to the guide-wire, so that while out of the way of the spindleit shall re-enforce the en traveler and throw, to, an adequate ext he twist given to the yarn by the latter bacf same hinged rail or board to which the guidewire is placed. By making the auxiliary device of small size as compared with the main traveler, I am enabled to bring it up close be-' neatll the guide-wire, Where it will act to correct inequalities of tension, and also to throw the full amount of twist back of the guidewire without danger of breaking the yarn, whether the latter be coarse or line, and where, also, it may be attached.. to the hinged guidewire rail or board, so that it may, along with the guide-wire, be turned up, back, and away t from, or down vertically above, the spindle, as occasion may require.

To enable others skilled in the art to make and use my invention, I shall now proceed to describe, by reference to the accompanying drawings, the best way known to me of carryingthe same into effect.

Figure 1 is a sectional side elevation of so much of a ring-spinning frame as is requisite for the purpose of explanation. Fig. 2 is a perspective view of the governing traveler-rin g and traveler and supporting-bracket detached.

a is the frame of themachine, having the drawing-rolls b, guide-wire c, lifting-ring rail d, ring c, traveler f, and spindle g, together with the usual bolster and step rails, which are not shown. The parts are of any ordinary or suitable construction and can be operated in the ordinary way.

At a point above the spindle or bobbin and below the guide-wire is located the device which I employ in order to carry my invention into effect. This device consists of a ring, h, of comparatively small diameter, provided with a traveler, i. The ring is so positioned that its center shall be directly in line with the longitudinal axis of the spindle, and the yarn, on its way from the guide-Wire to the traveler and spindle, (or the bobbin or coptube thereon,) passes down through vthe traveler, as shown in the drawings. This regulating-traveler is placed a short distance-say three-quarters ot' an inch, more or less-below the guide-wire, and is held in position on the guide-wire rail by any suitable means. The distance may be varied, but that above stated will give the best results. The means employed in this instance to hold the regulatingtravelerin place consists of a bracket, j, which carries the ring h, and is secured to the under side of the thread-board. I prefer to adjustably connect the bracketwith the threadboard, so that the traveler-ring h can be accurately set, and to this end I fasten it by means ot' a set-screw, 7c, which extends into the threadboard through a slot, l, in the horizontal arm of the bracket. I also prefer to detachably fasten the governin g-rin g to the bracket-as, for instance, by ascrew,m-in order that when one ring becomes worn it may bc removed and replaced by another.

When the machine is in operation the yarn between the regulating-traveler and the main or ordinary traveler is thrown outwardly by centrifugal action,and will put the regulatingtraveler in rapid rotation, the rate of movement of said device increasing and decreasing with the increase and decrease ot' tension on the yarn drawn through it. It therefore acts, in a measure, as a governor' or regulator, and

or board, and the main ring and traveler, of 4o an auxiliary traveler and traveling ring, attached to and carried by the hinged guide-wire rail or board, and placed vertically above the spindle and below the guide-wire, substantially as hereinbefore set forth.

2. The combination, with the rolls, the guidewire, its hinged rail or board, and the main ring and traveler, of the auxiliary or regulating traveler and ring adjustably secured to the guide-wire rail, substantially as shown and set forth.

In testimony whereof I have hereunto set my hand this 22d day of October, A. D. 1880.
